When working in normal slide editing mode, and entering multi-lined text into 
a text box, the movement of the actual curser does not cause the column 
location displayed on the infobar at the bottom of the window to update.  You 
must jiggle the mouse to get an updated location of where your curser is.

1 To replicate this, do the following:

2 Create a text box.

3 Type an abitrary line of text and hit enter.

4 Type another line of text longer then the first and hit enter again.

5 Provided the mouse does not move during this, the value of the column will   
remain unchanged.

6 Then move the mouse, the column location will update.

It is also worthwhile to note that if your text box leaves the workspace area, 
the row will cease to update without mouse movement
